HTTP Headers Features: autoplay

Hello friends! Today we want to discuss one of the interesting and useful features in HTTP Headers called Feature-Policy and specifically the autoplay feature. These features provide us with the ability to have better control over the resources used in the web pages we utilize.

The autoplay feature specifically is responsible for automatically playing videos or audio in the browser. You may have encountered a situation where you open a site and suddenly a video starts playing automatically, catching you off guard. This capability is designed to prevent such occurrences.

Using the Feature-Policy can have a significant impact on user experience and resource usage. By precisely controlling features like autoplay, we can ensure that only those cases that absolutely require it remain active. This can help reduce bandwidth usage and also enhance page loading speed.

To use the Feature-Policy, you need to add the name Feature-Policy to your HTTP response. For example, it indicates how you can perform this task:

Feature-Policy: autoplay 'none';

In the above example, we have disabled autoplay globally for the page. This means that no video or media that exists on the page can be played automatically.

Why should we use this feature?
Generally, using Feature-Policy and managing features like autoplay can enhance the security and functionality of your sites.
